The IPv6 address can then be used to send an IPv6 ping request from another VERA-P1 module over 
the 

llc-cch-ipv6 interface: 

$ ping6 -I llc-cch-ipv6 fe80::8a8c:22ae:976d:cdde 

The throughput over IPv6 between two VERA-P1 modules can be tested using the iperf3 tool for 
example. To do this, start the iperf3 server on one side: 

$ iperf3 -s -D 

Then start the throughput test on the client side and connect to the IPv6 address of the server: 

$ iperf3 -6 -c fe80::8a8c:22ae:976d:cdde%llc-cch-ipv6

Building the software for a different target platform 

Building the LLC Remote package for a different target system requires a toolchain and configured 
kernel sources for the target platform. The following example shows how to manually cross-compile 
the  LLC  driver  and  tools  for  an  Arm

®

  architecture  using  the 

gcc-arm-linux-gnueabi  toolchain.  The 

configured kernel sources should be available in the 

/home/duser/work/linux-3.10.107/ directory. 

 

Recipes for integrating the software package into Yocto-based projects can be provided by u-blox 
on request. 

To cross-compile the LLC driver: 

$ cd cohda/kernel/drivers/cohda/llc 
$ make BOARD=mk5 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- 
KERNELDIR=/home/duser/work/linux-3.10.107/ 

To cross-compile the LLC tool, library, and plugins

6

$ cd cohda/app/llc 
$ make BOARD=mk5 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- CC=arm-linux-gnueabi-gcc 
LD=arm-linux-gnueabi-ld 

After successful compilation, the following files must be deployed on the target system: 

 

cohda/app/llc/llc – LLC tool 

 

cohda/app/llc/lib/libLLC.so* – LLC library 

 

cohda/app/llc/plugin/*.so – LLC plugins (to plugin subdirectory) 

 

cohda/kernel/drivers/cohda/llc/cw-llc.ko – LLC kernel module 

 

cohda/kernel/drivers/cohda/llc/SDRMK5*.bin – SDR firmware images 

The 

dfu-util  tool is required on the target system  to download  the SDR firmware to the VERA-P1 

module. 

 
 

                                                                 

6

 Not all plugins are provided as source code. The Binary plugins are available only for i686, x86-64 and mk5 (Arm) architectures.
